I didn't really get the impression that Tenshi was taking the fight against Yukari any more seriously. She probably at least half knew that her whole 'stick a keystone in the hakurei shrine' plan wouldn't work. I don't think she really gets serious until her route and even then, the dialogue kind of makes it sound like Reimu's the only one who she really took seriously, because Reimu's instincts told her that Tenshi didn't lose on purpose.
